NAMEarping - send ARP REQUEST to a neighbour host
arping [ -DUAq] [ -c count] [ -w deadline] [ -s source] -I interface destination
- The same as -U, but ARP REPLY packets used instead of ARP REQUEST.
- -c count
- Stop after sending count ARP REQUEST packets. With deadline option, arping waits for count ARP REPLY packets, until the timeout expires.
- Duplicate address detection mode (DAD). See RFC2131, 4.4.1. Returns 0, if DAD succeeded i.e. no replies are received
- -I interface
- Name of network device where to send ARP REQUEST packets. This option is required.
- Quiet output. Nothing is displayed.
- -s source
IP source address to use in ARP packets.
If this option is absent, source address is:
- In DAD mode (with option -D) set to 0.0.0.0.
- In Unsolicited ARP mode (with options -U or -A) set to destination.
- Otherwise, it is calculated from routing tables.
- Unsolicited ARP mode to update neighbours' ARP caches. No replies are expected.
- -w deadline
- Specify a timeout, in seconds, before arping exits regardless of how many packets have been sent or received. In this case arping does not stop after count packet are sent, it waits either for deadline expire or until count probes are answered.
